Well, sorry about that. My response is from a Technical point of view. I didn't know the promo has those conditions. Maybe if you are user of a discontinued plugin something can be done. Try to explain your situation to sales, I hope they find a solution.

I'm pretty positive that forbidding customers the usage of older software versions is illegal, at least in the EU zone.
Of course one should not run V3 and V4 at the same time.

I use multiple 3d apps - FormZ, Rhino etc...

I use the plu-in for each app to:
a) sometimes render directly within the app,
b) sometimes to create an .mxs that I open in Studio and then continue working in Studio, perhaps adding other .mxs files that have been created with the other 3d apps.


With the new licensing arrangements where Maxwell is tied to a particular 3d application,
looks like I'm being forced to buy as many licences of Maxwell as number of apps that I use for 3d modelling? i.e one licence for Maxwell/FormZ, another licence for Maxwell/Rhino, and so on

and then on top of that one licence for Studio!?

I suppose I will just have to export/import geometry from all my apps to the one single app that I choose to be the Maxwell licensed one. Not exactly helping streamline workflows is it.

One most important thing:

"If there is not enough memory in the GPU the render will fail unfortunately, for the moment there is no way for it to use regular RAM" - Maxwell Render facebook

So your scene have to fit in your VRAM.

Is technically possible to use also RAM for GPU rendering ?

I don't know how other CUDA based renderers works, but is it technically possible to use also RAM ?

Well, depends on what we use it for. For example, trying to make a huge render (imagine 12k or some crazy thing like that) can be done dividing the image in regions, and using RAM to fit a lot of buffers of the final image, so that the GPU doesn't explode. On the other hand, using RAM to store scene information that doesn't fit on VRAM is a very bad idea. Any ray can rebound against a part of the scene that is not hosted on VRAM in that moment, and you need to do the swap between RAM and VRAM for that info. I think it will be slower than rendering on CPU.

Just theorical thoughts. Don't take it as an stament.

Thanks for informations Luis, another thing which makes me really curious is, MultiLight in Fast Mode is still based on OpenCL ?

Because I have Titan X with 12GB of VRAM and I still can't use it properly - here is thread about the issue

Fast multilight on Maxwell render it's the same OpenCL one. Fast Multilight on multilight app it's a new CPU versión of Fast Multilight.

Great,

and can you tell us if SSS is implemented now in GPU version or it will be added later ?

Well, the roadmap of what's done, what's going to be done and when it's going to be public on launch. Better wait for that, I don't want anybody here to get angry at me

As far as i know:
- Redshift has out-of-core rendering using the system RAM for textures and geometry. No info about performance.
- Octane can use the RAM only to store the textures. They say it can be 10-20% slower.

i have a question... If i own 3.2 and i upgrade with this promo to 4.0 do i lose the right to use 3.2?

No, you will maintain your v3 license and get a new v4 license. If you install them both on different directories you can even run them at the same time (something I used to do to compare some v3 vs v4 behavior during development).

Sorry are you sure about this? Because i was just told otherwise.
Here is a comment from Nextimit Maxwell Render Facebook Page regarding this topic.

"Massimo Galluzzo if i have a 3.2 license and upgrade to 4, will i lose the ability to use 3.2?"

"Maxwell Render, The Light Simulator Hi Massimo! Yes, as with any upgrade when you get the new version with a discounted price you don´t have the old one anymore. If you would like to keep both, you will need a new license. In any case an upgrade is the best option, as V4 will have both the CPU and the GPU render options."

I am sorry but this is really crazy. So i have just bought 3.2 with this promo which by the way is the last version that has a plugin for Softimage, i upgrade to 4 and i lose the rights to use 3.2? So i will find myself with version 4 only, with no plugin, and i would have to pick between Studio only or another 3d package version which i dont have.
What is this? If i knew this before i would have never bought the commercial version. This is like forcing and choking customers.
Guess i learned my lesson.

I asked about this a little more. Licenses of v3 and v4 work fine together. Save your v3 license, and should be no problem having both v3 and v4 licenses from upgrade. What is limited is activation, but your v3 license is already activated.

very good because I always can't to use gpu multi-light on my 6g vram!

"limited"? How? So that i can't activate v3 on a new system?

[burnin]

Seems like a downgrade... one GPU per machine, plugins gone (Houdini... Blender not even considered), no previous version for use... thank you for the offer!

[T0M0]

MultiGPU is planned and development roadmap should be also released.

I'm not Blender user, but dropping three plugins support (XSi, Houdini and Lightwave) could bring at least a new one and make a lot of Blenderians happy. just my two cents...
